“Blood Moons” will be released nationwide March 18. The documentary, also featuring Biltz, will be released the same day.

An extraordinary chain of events in the heavens begins this Passover, April 14.

It’s called a “blood moon tetrad,” an astronomical series of lunar eclipses that has occurred thousands of times in history, according to NASA. But there’s something very different about this series, because the eclipses occur on the biblical holidays of Passover and the Feast of Tabernacles, or Sukkot.

When tetrads have occurred in the past on these holidays observed by Jews around the world and an increasing number of Christians as well, they have coincided with momentous events in the history of the Jewish people.

As Passover nears, millions of people around the world are watching with anticipation for the moon to turn blood red with the first eclipse.

But Biltz said that to understand the meaning, it’s important to know the seasons, feasts and calendar of the Lord.

Biltz, founder of El Shaddai Ministries, is a well-known commentator on the feasts of the Lord who has spoken in Sweden, Germany, Switzerland, Canada and throughout the United States.
